Is Invoice Generator free to use?

Yes. Invoice Generator is available on the free plan with 20 daily runs. Paid plans add higher quotas for repeat work.

What has to appear on an invoice for it to be valid?

Most jurisdictions expect a unique sequential number, both parties' names and addresses, tax registration numbers where you are registered, the date and description of the supply, the net amount, the tax rate and amount, and the total. Requirements vary, so check your tax authority's list.

Is a generated invoice summary legally binding?

It records what you are charging, but it is not a contract and it does not replace your accounting records. Whether it satisfies a tax authority depends on the mandatory fields and your registration status, so keep sequential numbering and your own copy.

Do I charge VAT on my first invoice?

Only if you are registered, and registration can become mandatory once turnover passes a threshold that varies by country. Charging VAT you are not registered for creates a problem you cannot fix retrospectively.

How should I word the payment terms?

Give an explicit due date, because net 30 and payment within 30 days are read differently by different finance departments. State any late payment interest or fee as well, since a statutory right to charge it is far easier to apply when the invoice mentions it.
